Setting the Camera view
Use the numpad keys to get the (orthographic) view you want
Numpad 1 = front,
Numpad 3 = side,
Numpad 7 = top,
Numpad 9 = flip (ex: top becomes bottom).
To toggle orthographic and perspective view use  Numpad 5
When you have the correct side, press Ctrl+Alt+Numpad 0 to snap the camera to your viewport view.
To get more specific, select the camera and press N to bring up the tool menu where you can adjust values manually (such as distance).
